What are the two methods of minesweeping?

• A. Mechanical and Influence
• B. Acoustic and Magnetic
• C. Mechanical and Acoustic
• D. Influence and Magnetic

Answer: (A)

Minesweeping is carried out using two broad approaches: mechanical sweeping and influence sweeping. Mechanical sweeping involves gear that physically interacts with mines along the path—such as tow devices that cut mooring lines or otherwise disable or remove mines, creating a safe corridor for ships to pass. Influence sweeping uses devices that generate fields or signals to mimic the presence of a vessel, triggering mines at a distance so they can be neutralized without contact. Magnetic and acoustic sweeps are specific kinds of influence sweeping, not separate broad methods, so the two main methods are mechanical and influence.
